Helen Haskell, founder of Mothers Against Medical Error, describes her son's fatal care in a new video.

The needless death of 15-year-old Lewis Blackman, son of national patient advocate Helen Haskell, is receiving renewed focus — most recently during a major health-care summit in California aimed at preventing medical mistakes.

Premiering there was a new video featuring Helen describing the wrenching details surrounding Blackman’s poor care in 2000 following elective surgery at Medical University of South Carolina.

The case, which I highlighted in a 2010 investigation, remains powerfully emblematic of one form of preventable patient harm — lax supervision of resident doctors by faculty physicians at teaching hospitals such as Parkland Memorial Hospital.
